Similarly one may ask, how big of a hole can you spackle?
Spackle can be used to repair holes less than 4 inches (10 cm) in diameter. Anything larger than that, and the spackle won't be strong enough to support itself and will collapse inward. Larger holes will require support like mesh or wire and joint compound to be properly repaired.
Considering this, how do you spackle a large area?
Holes larger than one inch across are considered large patches, so follow these directions to spackle and finish a large hole so it will virtually disappear.
- Step 1 - Wash the Wall to Remove Existing Grit.
- Step 2 - Put on Your Face Respirator Mask.
- Step 3 - Fill the Large Hole.
- Step 4 - Sand the Spackled Patch.
The big difference between spackle and joint compound is the scale in which they might be used. While joint compound can be used for anything from sealing joints, to prepping drywall for its first coat of paint, spackle is going to find its application for much smaller household uses.
